Because of the similarities between tooth enamel and eggshells, you can use hard-boiled eggs to demonstrate proper dental hygiene to your child.
You'll need: hard-boiled eggs (preferably with white shells), dark-colored soda, toothbrush, toothpaste containing fluoride, a jar or cup, and vinegar.
🥤 The Soda Experiment
- Boil 2 to 3 white eggs. (The shell needs to remain intact, so having an extra helps.)
- Fill a small jar or cup with dark soda. As a side experiment, fill one jar with regular soda and one with diet soda to see if there's a difference in how each affects the "tooth." Place a hard-boiled egg in each cup and leave it overnight.
- Check the egg in the morning and discuss the stains on the shell. Talk through the connection between eggshell and tooth enamel, then ask your child what they think they can do to remove the stains with a brush and toothpaste.
🍶 The Vinegar Experiment
- Give your child a hard-boiled egg and let them crack it open if they wish. Ask what purpose they think the shell serves. Explain that the hard shell protects the soft egg inside, just like enamel protects teeth.
- Fill a jar two-thirds full with vinegar — the vinegar represents the acid from plaque that forms in our mouths.
- Put a hard-boiled egg in the jar, cover it, and leave it in place for up to two days. Remind your child periodically how leaving the egg in the vinegar is like a person not brushing for two days.
- Remove the egg after two days and have your child note how the shell is soft and pitted.
